    Because here Acidic medium is given so hydrolysis of ester also possible which gives carboxylic acid on hydrolysis

    so acidic medium kahan Diya hue only base aur heat Kiya houa

    Last step is decarboxylation step(release of CO2).. when there is beta carboxylic acid then on heating decarboxylation occurs.

    sir m not asking this

    eduncle-logo-app

    first example mein condensation product final answer hai lekin in second example unhone condensation product ke bad hydrolysis Kiya hai FIR decarboxylation Kiya hai aisa kyon

    eduncle-logo-app

    shweta hydrolysis given honge then first diacid form hoga fr decarboxylation hoga

    eduncle-logo-app

    first example MI FIR aisa kyon nahin kiya

    eduncle-logo-app

    hydrolysis nhi given hai condition me

    eduncle-logo-app

    but generally last step tak proceed krte hai kyunki diacid form hote hai or decarboxylation favour krte hai
